Metalcasting involves having a molten metal poured in a hollow mould to produce metal objects. These moulds are generally made of sand and are chemically bonded, clay-bonded, or even unbounded. There are many binder systems used. Binders based on furfuryl resins constitute currently the highest fraction in the binders no-bake group. Moulding sand, after knocking out the cast, is partially recla...

Polycarbonate foams reinforced with 0,5 wt% of graphene were obtained by firstly melt-mixing the polycarbonate and graphene in an internal mixer, compression-moulding the melt-compounded grinded material and lastly dissolving CO2 inside a high pressure vessel. The CO2 desorption behaviour in the unfilled polycarbonate and nanocomposite was studied in terms of the CO2 saturation concentration an...

Woven fabric reinforced composite materials are typically applied in plate or shell structures, such as ribs, stiffeners and skins. Products of this type can be manufactured with several processes. A few examples are compression moulding, diaphragm forming, matched metal die forming and Rubber Press Forming (RPF). Shape distortions can occur during manufacturing of composite products. During th...

The production of castings by green sand moulds is a very important method for the manufacture of final products for different sectors of industry. In this green sand moulding process the quality of castings depends strongly on the quality of the mould, which in turn is determined by parameters such as the type of foundry machine, the characteristics of the moulding sand and the specifications ...

Article history: Received on: 06/01/2014 Revised on: 22/01/2014 Accepted on: 12/02/2014 Available online: 27/02/2014 Orally disintegrating tablets (ODTs) have greatly increased dosage forms which have remarkable impact on the patient compliance especially for the pediatric, geriatric and psychiatric patients with deglutition disorders. Several technologies either conventional or patented based ...

Highly environmentally-friendly fibreboards were manufactured by hot-press moulding using Posidonia ocaeanica wastes and a partially biobased epoxy resin as binder. Fibreboards with a constant fibre content of 70 wt % were successfully manufactured by thermo-compression. The effects of a conventional alkali treatment were compared to the synergistic effects that additional silanization with two...

Thermoplastic compression resin transfer moulding coupled with injection is an appealing process for the production of thermoplastic composites. However, its implementation at industrial scale remains challenging as variotherm could prevent solid skin formation in parting line, making cavity sealing difficult. In this study, a tool and related methods parameters are presented. The validity conc...

Abstract Aiming to further plastics recycling via rotational moulding processing, blends of virgin and recycled polyethylene sourced from post-consumer were developed. Three different kinds high density – bottles, pipes mixed household waste compounded with medium in an extruder. The ideal amount recyclate was chosen based upon the impact resistance contents (25, 50 75%) plastic 50/50 blend fou...
